Together with Cospal Composites we carried out the structural optimization of their bonded aluminum panels for radiotelescopes reflectors. In this way Cospal Composites propietar technology has been pushed to the limit of few microns rms surface accuracy: the numerical predictions have been verified by factory and field metrology. Again with Cospal Composites we designed a class of off-axis aluminum reflectors for antenna Beam Wave Guides as well as main optics.ADS also was technical representative of ANTEDO, Inc. for the construction of structural and mechanical components of several of their antenna (21 m KVN radiotelescope shown here).Recently ADS developed a new linear actuator for LMT-GTM active primary reflactor system.
